Proto: Buy low, sell high (AI=2)
Create a Power-1 Rule titled "Stocks":
The following Stocks exist:
Abbr. Name
----- ----
CFJ Collaborative Finance Journal
PDF Power Dance & Fitness
PGP Pineapple Growers' Partnership
RR Renascent Ribbons
WGS Wright Goods & Services
Create a Power-1 Rule titled "Properties of Stocks":
For each Stock, Holdings of that Stock is a player switch whose
value is a nonnegative integer, default 0.
Intrinsic Value is a Stock switch whose value is a nonnegative
integer, default 1.
Market Value is a Stock switch whose value is a nonnegative
multiple of 0.2, default 1.
The Brokor is an office; its holder tracks all switches defined
in this rule.
Create a Power-1 Rule titled "Buying and Selling":
A player CAN Buy a specified Stock by announcement: the Stock's
Market Value is increased by 0.2, e pays Agora the new Market
Value in shinies, rounded down, and eir Holdings of that Stock
increase by 1.
A player CAN Sell a specified Stock by announcement: the Stock's
Market Value is decreased by 0.2, Agora pays em the *previous*
Market Value in shinies, rounded down, and eir Holdings of that
stock decrease by 1.
The above notwithstanding, a player CANNOT Buy or Sell if one of
the component actions would fail (including Selling with 0
Holdings).
Create a Power-1 Rule titled "Turning the Crank":
Turning the Crank (which SHOULD be performed weekly, see below)
causes each Stock's Intrinsic Value to change according to a
Random Decision as follows:
Chance Result
------ ------
35% Move by 2 in the direction of Market Value.
30% Move by 4 in the direction of Market Value.
30% Move by 2 in the opposite direction of Market Value.
5% Reduce by 50%, rounding up.
(Moving by X in the direction of Market Value means increasing
by X if less than it, or decreasing by X if more than it, even
if the result overshoots; vice versa for moving in the opposite
direction.)
Furthermore, it increases each player's Balance by the sum of,
for each Stock, eir Holdings of that Stock times its Weekly
Dividend, rounded up after the final sum. A Stock's Weekly
Dividend is equal to half its Intrinsic Value.
Cranks Needed is an integer Agora switch, tracked by the Brokor,
initially 0. At the beginning of every week, Cranks Needed goes
up by 1, to a maximum of 3. When Cranks Needed is greater than
0, the Brokor CAN Turn the Crank by announcement. In a given
Agoran Week, the Broker SHALL Turn the Crank until Cranks Needed
is 0.
Create a Power-2 Rule titled "Random Decisions":
The rules may define a process initiated by announcement to
include a Random Decision, specifying a range of possible
results and associated probabilities. This means that the
person CAN select any of the possible results by announcement in
the same message as initiating the process, and CANNOT initiate
the process without doing so. Furthermore, e SHALL make the
selection randomly, following the associated probabilities and
independently from any other random decisions, using a method
that allows any other player to reasonably verify e has done so
correctly (e.g. dice server).
